Title: Semiconductor memory device
Inventor: AKIMOTO KAZUYASU
IPC: G11C11/414
Filed: 1984-04-13
Abstract: PURPOSE:To prevent malfunction of memory and to shorten the access time by providing a circuit for latching a complementary data signal from a memory cell in a read circuit. CONSTITUTION:A circuit 11 for latching readout data by a read circuit 1 having a transistor, which comprises a current switch circuit together with a transistor in a memory cell MC, is added. Although higher node levels in a memory cell previously selected and that selected this time drop simultaneously below a read reference voltage, previous data is provisionally stored in the circuit 1 by setting a double selection margin; therefore, when the same binary data is continuously read out, currents cannot flow simultaneously to a pair of common digit lines CD from a level shift resistance in the circuit 1. Thus switching noises can be removed from an output waveform and the access time can be shortened.

IPC: G03G21/04
Filed: 1993-03-09
Abstract: PURPOSE:To precisely count a job time required for copying by detecting the initial operation of the copying job and the end of the copying job. CONSTITUTION:An operation detection section 20 monitors the state of the machine or the like and sends operation information to a copy operation section. A copy start detection section 21 detects the start of copying by detecting the operation of an operation tray selection key and outputs start information to a timer 23. Moreover, an end detection section 22 detects the end of copying by depressing a stop key after the end of copying and provides an end information output to the timer 23. Upon the receipt of the start information from the detection section 21, the timer 23 is started and stops the operation by the end information from the detection section 22 and provides a count information output to an arithmetic section 26. The arithmetic section 26 multiplies the count information from the timer 23 with unit price information from a unit price decision section 24 and sends man hour cost data required for the copying job to a storage section 27. An output section 28 gives information for each copying from the storage section 27 to a printer or a display device.

Title: Automatic buckle device
Inventor: MIYAUCHI KIYOTAKA
IPC: A44B11/25
Filed: 1993-03-31
Abstract: PURPOSE:To enable the tongue of a seat belt device and a buckle to be automatically coupled. CONSTITUTION:A tongue 2 can be inserted into a buckle 4 in a no-load state (without resistance) by the function of an eject solenoid 78. A limit switch detects the position of the tongue 2 to actuate a latch solenoid 66 and automatically brings about a latch hold state. When the latch solenoid 66 is reactuated, an eject spring 86 is energized, so that the tongue 2 retreats from the buckle 4. Therefore, when the tongue 2 is inserted into the buckle 4, the tongue and the buckle are automatically coupled and latched. A switching operation can release this latch. Thus, the tongue and the buckle can be very easily attached and released.

IPC: G21C7/00
Filed: 1988-03-30
Abstract: PURPOSE:To realize a smooth load following operation of a nuclear reactor, by controlling a intermediate check valve by a load demand signal, making an output of a turbine generator follow the load demand and controlling an extraction valve so as to suppress a pressure deviation in a moisture separator. CONSTITUTION:A signal 78 is a controlling error signal to equalize a pressure PMS to an approximately constant signal 77. The signal 78 is fed to a regulator 28 having functions of proportioning and integration, and therewith an extraction value (EV) 27 is operated accordingly. Moreover, a mode in which a reverse demand against a function demand of an IV valve is fed to an accumulator element 42 as a forwarding control demand signal 76 in a block 52, is obtained by making the mode effective by operation of a switch 47. In this condition, a signal 72 is zero, and as the pressure PMS is approximately constant, a control valve (CV) 24 is not activated and an output sharing rate of a high pressure turbine is also constant, therefore, a pressure Pr does not change. As a result, because a reactor dome pressure Po to which a neutron flux responds most sensitively stays being unchanged, the most preferable operating condition can be attained.
